.S'OLEA/O/D United States Patent 3,336,024 DEVICE FOR SHINGLING AND GLUEING PAPERS Hyman Brechner, 65 Bella Vista Road, Tuckahoe, N.Y. 10707 Filed June 15, 1965, Ser. No. 464,085 8 Claims. (Cl. 27053) This invention relates to shingling devices and more particularly for a device for holding papers while being shingled while applying glue to the margins of individual papers, during the assembling of a plurality of separate sheets into a set.

It is an object of the invention to provide a device of the kind described which will accurately align a plurality of sheets of paper as to all corresponding edges and hold them in proper position while glue is being applied in a predetermined position to an edge of each sheet in sequential order during the course of adding sheets to a set.

It is another object of the invention to provide a gluedispensing device which will have the dual function of effecting equal and even pressure all along the glued edge of the sheets, in order to insure evenness of glue application and regularity of sheet registration in the set.

It is a still further object of the invention to provide a device which can be used by unskilled labor for a rapid shingled assembly of a plurality of sheets into sets.

Other objects and features of the invention will be apparent from the description to follow.

Briefly, the invention comprises a work table having a plurality of aligned perforations through which pins carried on a common bar are moveable, over which pins the perforate edges of sheets are placed for shingling alignment. A component of the invention comprises a glue applicator which is also a device for firmly and evenly pressing the perforate edges of the sheets down against the work table so that misalignment, normally present when manual finger pressure is used, can be eliminated. The construction is such that each sheet is placed on the pegs and shingled with reference to the preceding sheet, a row of glue dots being applied in predetermined position to the edge of each sheet prior to the subsequent sheet being placed thereover. The pins are then withdrawn from below the table surface on which the sheets rest and the sets of sheets thus adhering together can be removed. The glue applicator comprises a well for glue and a plurality of valve needles protruding through nozzles at the bottom of the applicator. When the bottom of the applicator is pressed against sheet margins, the valve needles are pushed upwardly to open the nozzles enough for escape or egress of a small amount of glue, each valve needle thus efiecting a glue dot at the perforate edges of the sheets. Lifting the applicator automatically causes the valve needles to close the respective nozzles. Further, the glue applicator has a bottom so constructed as to be usable for applying firm and even pressure to the set of sheets, while the pins are being Withdrawn. The bottom comprises a wall of plate having perforations corresponding to the pins of the work table so that such pins can pass through the bottom plate when the bottom plate is brought to bear on a set of sheets held by the pins. The perforations on the bottom plate have the further effect of predetermining the exact position of the glue dots on the sheet. A further efiect is that these glue dots may be placed close to the positioning pins without having the glue smear the pins. This smearing is a common fault with hand operations.

In prior glueing applications the glue dots are applied prior to the positioning of the sheets on the pins. Transporting the glued sheets to the pins usually results in difi'iculty in accuracy in alignment since the sheet being transported may adhere to the sheet or sheets below before accurate alignment is effected.

The invention is semi-automatic in nature in that the row of pins may be pneumatically actuated or actuated by a solenoid while the glue applicator is a manually manipulated component. Further, the components of the invention are adaptable to fully automatic operation.

A detailed description of the invention now follows in conjunction with the appended drawing in which:

FIG. 1 is a perspective showing a single set of sheets in glued adherence, this being the final product of the invention.

FIG. 2 is a plan view of the invention showing the work table and a series of sheets carried thereon.

FIG. 3 is a section through 33 of FIG. 2.

FIG. 4 is a section through 44 of FIG. 2.

FIG. 5 is a fragmentary view similar to FIG. 4 showing the pins in lowered position so that a set of sheets may be removed from the work table.

FIG. 6 is a perspective view of the glue applicator taken primarily from the underside to show details of the glue nozzles and pressure plate.

FIG. 7 is an elevational cross-section taken through the glue applicator and the work table showing the relationship of the two components in the course of applying glue dots to sheets.

FIG. 8 is an elevation partially in section showing the mode of using the glue applicator bottom plate for effecting pressure on sheets being held by the pins.

FIG. 9 is a cross-sectional view of a modification wherein movement of the pins is effected by an electromagnetically operated plunger.

Referring now to the drawing, the perspective view of FIG. 1 illustrates a plurality of sheets 10 which have been shingled by a predetermined amount at their lower edges, such sheets each being provided with a row of perforations 15 of the usual kind 'which are used in the shingling method of the invention and which are also used when the set is held in a looseleaf binder or on a pegboard in the course of making entries as in a payroll system or the like.

Referring to FIG. 2, a work table 20 is illustrated having a holder comprised of a series of guide angles 23 in rectangular array in which is kept a stack of sheets 10 in preparation to be individually picked up by an operator and placed sequentially in shingled array with their perforate margins on a stripper plate 27. The stripper plate comprises :a plurality of apertures 30 having the same spacing and general shape as the apertures 15 of the sheet and also comprising a trough 34 for a purpose tobe hereinafter described.

Below the stripper plate 27 there is disposed a pinholding bar 37 to which is secured a pin means such as a plurality of pins 40 which extend upwardly, and it will be noted by comparison of FIGS. 4 and 5 that the pins can protrude upwardly through the sheet perforations 15 or be withdrawn downwardly so as to free the sheets.

The bar 37 is carried on a piston rod 44 being adjustably threaded thereon at the rod end 47 and with an adjusting nut 50 is provided for the purpose of adjusting the position of the bar on the piston so that the pins 40 will protrude a predetermined distance above the stripper plate depending upon the number of sheets or the number of assemblies of sheets to be assembled into a set or sets. The piston 44 is actuated by a pneumatic cylinder 53 of any suitable commercial type having a spring 54 for biasing piston 56 for return, i.e., upward movement. A conduit 60' carries air under pressure to the cylinder and it will be understood that the air is suitably valved for control purposes in any conventional manner. The top of the cylinder may carry a stop plate 64, which is stationary with the cylinder, and the ends of which plate carry respective adjustable stop screws 67 and locking nuts 70. Thus the tops of the screws may be set a pre determined distance with respect to the stop plate to limit the downward movement of the bar 37 under air pressure in the cylinder whereby the tops of the pins 40 will be certain to recede below the stripper plate in order to insure freeing of the sheets resting thereon. For rigidity, the stop plate 64 may be secured by brackets 73 to the bottom of the Work table 20, as shown in FIG. 4.

From the above description, it will be apparent that under operator control, the pins will be maintained in raised position by the pneumatic cylinder spring or air valve while sheets are being placed in shingled array on pins 40 as illustrated in FIG. 3. During the shingling process, glue is applied to each of the sheet edges as will presently be described, it being understood at this point "that subsequent to the set being made up or" shingled sheets, air pressure is valved into the cylinder to push the piston downwardly, thereby withdrawing the pins from the apertures of the sheets, whence the set may be removed from the work table.

Referring now to FIGS. 6 and 7, the glue applicator comprises a member having a storage well in the form of a block-like housing 80 having a cover 83 which may be fastened thereto in any suitable manner. The housing effects a glue reservoir 86 having a separate bottom wall 87 suitably bored as at 88 to provide a series of passage ways for respective tubular nozzles 90 threaded into housing 80. Each nozzle has a restricted lower end opening or port 92 and a substantially cylindrical tubular shank. Each such nozzle carries a valve needle 95 having a tip 96 coacting with the respective nozzle openings 92. The weight of the needle valves is relied on to maintain the tips thereof in closing position with respect to the nozzle openings 92. However, in such position, the needle valve ends 96 protrude a fraction of an inch as seen in FIG. 8. Accordingly, it will be understood that when row of valve tips are pressed down against a surface, the valve needles will be pushed up to permit a drop of glue to emerge at the restricted open ends 92.

The glue housing is provided with a groove 98 of suliicient height and proper lateral dimensions so that the pins 40 can protrude thereinto when the glue applicator bottom wall 87 is pressed against sheets as illustrated in FIG. 7, for applying pressure to a set subsequent to shingling assembly and prior to removal from the pins, as subsequently described.

The bottom wall or plate 87 has aperture means, being guide apertures 106 which are registerable with the apertures in the sheets and permit respective pins 40 to protrude through the bottom plate into the groove 98 when glue coating dots thus spaced from the perforations are applied to the sheet margins.

A further aperture means such as a row of apertures 110 is provided in the bottom plate extension 112 to permit the glue applicator to be used as a pressure plate on the last sheet of the set in the manner illustrated in FIG. 8 after all the other sheets in the assembly have had glue applied to them.

Each sheet in pile 10 is laid onto the pins 40 and the glue applicator is pressed on each sheet in turn, the glue dots being deposited only on the sheet being pressed down as the bottom plate applies even pressure thereto.

Apertures 106 are used until the top sheet of the assembly is placed on pegs 40. This sheet needs no glue so that by shifting the glue applicator apertures 110 are placed over pins 40 and the applicator pressed down.

From FIG. 8 it can be seen that valve tips 96 are accommodated in trough 34 and are not engaged in any way. In this manner several sets may be placed on pins 40 and will not adhere to each other.

Usually the sheets used in this assembly are of a considerably narrower dimension on the aperture edge than their length. The importance of evenly applied pressure to the edge containing the apertures will be evident from the fact that uneven pressure causes the sheet to become misaligned in the set, causing subsequent misalignment with the lines of ledgers and journal sheets when the shingled assemblies are used therewith on a pegboard.

It has been found that this method is greatly superior to the prior method of pressing the sheets down with the fingers. Thus the prior method causes unevenness and shifting of the sheets. When it is considered that there may be many sheets to a set, such unevenness can take on a serious character.

The application of even pressure parallel to the board 20 insures alignment of the sheets of a set even if the length of the sheets is many times the width.

The danger of misalignment is also avoided by the method of glue application since glue dots are applied to all sheets in exactly the same position. The danger of the glue smearing the positioning pins 46 is eliminated. This eliminates the possibility of the glue causing the sheets to skew with respect to each other or adhere to the pins 40.

Also, because the bar 37 is depressed parallel to both plate 2!} and assembly 10, further possibility of misalignment is avoided. This movement downward in parallel relationship applies even vertical drag and thus avoids skewing of sheets on which the glue is still not set. Also because the movement of pins 40 is simultaneous and in parallelism, the number of sets which may be assembled on pins 40 is greatly increased over those methods where the assemblies are stripped off by lifting them at one end and pulling them off the pins slantingly.

Referring now to FIG. 9, a modification is illustrated wherein an electromagnetic solenoid is utilized to efiect reciprocation of pins 40. Thus the solenoid may be secured to the plate 64 in turn secured by brackets such as 73 to the Work table 20', all as previously described. In this instance, however, the solenoid plunger 124 is fastened to a rod 127 adjustably threaded to the bar 37 which carries pins 40. The adjusting nut 50 is utilized in the same manner as herebefore described for adjusting the height of the pins relative to stripper plate 27. Upon energization of the solenoid, plunger 124 causes pins 40 to rise upwardly to the position shown in FIG. 9, all for the purpose hereinabove described. In this instance the bar 37, pins 40, etc., may drop by gravity when solenoid 120 is deenergized.

Having thus described the invention, it is realized that changes may be made without departing from the spirit thereof and, therefore, it is not desired that the invention be limited to the precise illustration herein given except as set forth in the following claims.
